Specification forming part of Letters Patent No. 154,221?, dated August 18, 1874; application filed June 13, 1874.

To all whom it may concern.' V

Be it known that I, JOHN H. GooK, of Hagerstown, in the county of Washington and State of Maryland, have invented a new and valuable Improvement in Feed-Rolls; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making aV part of this specification,` and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a front viewof my feed-roll, and Fig. 2 is an end view. Fig. 3 is a sectional view.

This invention has relation to means for fastening and securing in placevthe elastic feed-rolls used in the "Keller or othergraindrill in which feed-rolls are employed. The novelty consists in collars. or disks of any suitable lnetal, which are applied upon a shaft close up against the ends of the elastic rolls, and are securely held in proper position by barring up the said shaft, whereby the feedrolls are prevented from endwise displacement, as will be hereinafter more fully explained.

In the annexed drawings, in which I have caused to be shownV only those parts of a grain-drill necessary to illustrate my invention, A designates the shaft for receiving the feed-rolls of rubber used in the Keller drill, and which is preferably rectangular in shape in cross-section. B designates an elastic-gum feed-roll, which is applied upon the rollershaft A, of which .rolls the number correA sponds to the number of the feed-apertures in the grain-hopper. O are metallic collars or disks, through which is constructed a central perforation, preferably of rectangular form, to permit of their being applied upon the shaft A, in close -contact with the ends of the gum feed-rolls B, against Which they are firmly -upset by ,means of lips or burrs a atl by Letters Patent, is-A The collars or disks O, applied upon a feedroll shaft, A, and rigidly held in place against the ends of au elastic feed-roll, B, by upset ting, substantially as specified.

In testimony that I claim the aboveI have hereunto subscribed my name in the presence of two witnesses.

JOHN H. COOK.
